Qualcomm 2560 x 1440 Mirasol smartphone screen

Check out this demonstration of Qualcomm's upcoming Mirasol displays at the SID Display Week 2013 expo. The most interesting prototye was a 5.1" panel with a resolution of 2560 x 1440, a pixel density of 577ppi! Besides the ultra-high resolution, this screen also has the advantage of using 6x less power than LCD and OLED displays. It's still a couple of years away from being ready for mass production though.We got a look at a previously announced 1.5-inch panel embedded on the top of an "always-on" smartphone and on the face of a smartwatch. Though a rep took care to emphasize that these were just mockups, he said the screen will soon show up in some third-party devices.

More interesting, though, was the company's next-gen display: a 5.1-inch panel sporting a stunning 2,560 x 1,440 (577 ppi) resolution. Viewed up close, it delivers crisp images, but the reflective display kicks back a silvery tint and colors don't pop as they do on other handsets.

Am I the only one that thinks some of these resolutions for mobile devices are kinda stupid?

Nope, I think it's insanity. On a screen up to 7" in size I think 1280x720 is ideal currently. In 5 years from now perhaps I'll think 1080p is more ideal, but not now. 1440p is absolute overkill which will be difficult to power and will be a serious drain on the battery.

I can see it both ways. It takes tech like this to push for improvements in other technologies (like batteries). One is always pushing the other. Though it seems like batteries have been the achilles for tech since the smart phone and electric vehicle. They need to step it up!

I think it's a pretty awesome screen. Should make other integrated displays (like in-dash displays for cars) a lot better.

Wouldn't that depend on what you're doing? This screen is designed for color e-readers, not pushing 1440p worth of gaming. My Nexus 10 is 2560×1600 and I get 8 hours of browsing the web and whatnot. This technology, since it uses significantly less power, would see probably near double that. 16 hours is pretty decent.

Apple did the research a long time ago and found out that anything over 320ppi @ 10 inches is pretty much the maximum of human eye. But the technology of the display also comes into effect. For instance Samsung uses a RGBG layout on it's displays which was clearly noticeable even at 300+ PPI from a distance. The S4 uses the same RGBG layout but because it's PPI is upwards of 400+ it's no longer noticeable.

Well yes, I think the pentile displays are horrible. I can't understand why Samsung hasn't already made it standard to have RGB even if one of the colors wears out faster... or whatever the reason is. My Atrix 4G (qHD) was pentile. After seeing normal 720p from my Nexus 4, its like heaven. I've seen the HTC One too, it's even better - if you hold it up to your nose. I still feel like something is lost even with high resolution pentile screens.
